How we did it?
With our new modular development hardware - currently wired here and there to be able to run this new screen:

We got a DP PLUG module, which is usable as sink or source:

For easier manipulation we put the module sideways and flipped it over:

We are not lazy to do a breakout board, rather impatient.
So we hand-soldered 12 wires to the 0.4mm pitch IPEX plug on the broken LCD's board
(which has its coupling capacitors removed so it does not interfere with the working screen
and we accidentally rip a pad off which renderd this piece of PCB unpowered):

Wiring-in the backlit using the disassembled strip from the broken screen
(from each of six LED strings a diode is removed so this piece is off, while the working screen is on):

The control unit - hard to explain that it is not an overkill :-)

Here comes the power. While the separate piece of PCB from a broken screen did work from 3.3V,
the complete new LCD assembly did not and exhibited a full white image. So we trimmed the PSU's voltage setup divider
and now it runs at 3.8V. It is highly probable, that the panel itself is designed to be powered from a 5V or even
higher power supply, as the consumption is over 1.5W:

The backlight controller needed a little modification too - change of the overvoltage protection to 50V
as the Retina screen got 16 while LED diodes in each strip:

This fruit goes for 9 watts (the backlit set at 18.5mA per string alone consumes 7 watts):

Grayscale test:
- the HP laptop's regular TN based screen has a blue tint (it does have FRC so the fade looks continuous)
- the Apple retina LCD has no tint and the gray is very natural and neutral

Color test (synthetic):
- front view: of course the IPS screen has a little wider gamut than a TN screen:

- view from top: the saturation on the TN screen is fading away even at small angle

Color test (ordinary use):
- the IPS screen is color rich and the 8 bit depth excels here
- the regular TN screen is just 6 bit and it can not recover the details - FRC generates just noise

- view from angle: the TN screen looses saturation and contrast, on the fingers a starting inversion is noticable:

- view from top: the TN screen exhibits strong color inversion:

All high PPI displays must have glossy finish as the matte film's grain size is similar to the size of the tiny pixels.
If such a film would be used, the scattering light can be observed as a noise - actually very color saturated noise which
totally ruins all the advantages of the screen (high bit depth, accurate colors, high resolution).
